Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed May 14, 190%. Serial No. 208,024.

'type which" are adapted to befolded into small compass and carried in a coat-pocket or val se and is soconstructed .that it will be light and strong, quickly opened and closed, I

and free from the annoyance occasioned by the entanglement of the ribs, a fault common to this and other types of umbrellas.

In the accompanying drawings, Fi ure 1 represents an elevation of my um rellaframe opened, the ribs being bowed as they would appear when covered. Fig. 2 is an enlarge view of the umbrella-frame closed. Fig. 3 is an enlarged vertical sectional view through the telescope-stick. Figs. 4 and 5 are detail views of the rib-joints in different positions. Fi 6 is a view of the joint from the inside. Flgs. 7, 8, and 9 are perspective views of the joints.

Similar letters refer 'tothe same parts on all the figures.

A indicates a telescopic umbrella-stick, to the upper end of which is attached a notchring F, in which supporting-ribs, hereinafter specifically described, are ivoted, they being expanded by the stretchers C, pivoted to said supporting-ribs and to a runner D. The handle is indicated by E. The stick. A is in three tubular parts-the lower section A, to which is attached a handle E, the upper section A bearing a notch-ring F on its top end, and the intermediate section A telescopically connected to the two end sections. The lower ends of. the intermediate and upper sections A A are enlarged externally to form shoulders a (1 respectively, which when the stick is extended abut against similar shoulders a a within the upper ends of the respective lower and intermediate sections A A. Aspring-catch a riveted to the inside of the intermediate section A projects through a slot near its lower end and engages the upper end of the lower section when the parts are extended. A similar spring-catch a holds the intermediate and upper parts in fixed position when drawn out. w 1

The runner D has its upper half fitted-to slide smoothly on the upper section A of the stick and its lower half enlarged, as at D, to

hinged together at B.

to the parts I just above the j oints permit the intermediate section entering thereinto when the umbrella is folded. A

notch-ring G is attached to the upper end of the runner D, inwhich notch-ring the stretchers C are pivoted at one end.

The cover-supporting ribs are each formed of two substantially equal parts H and I, The inner end of part H of each rib is pivotally connected to the notch-ring F, while the outer end of each part I is perforated to receive the thread by which the cover is secured to the ends of the ribs, The stretchers C, pivoted as hereinbefore mentioned to the runner D, have attached to their outer ends joint-tips 0, right angular in shape and connected by in-joints l3 of the ribs. (See Figs. 7 and 8.) The joint B between the rib parts H and I is constructed as clearly shown in Figs. 6, 7, 8, and 9, where it will be seen that the ointed ends of the parts H and I are secured in sockets H and I, respectively. The socket I-I, longer than I, has a hook-shaped finger h at one side which extends under the rib I to limit its movement and give it support when the umbrella is opened. The sockets H I have lugs projecting downwardly from their adj acent sides through which the pivot pin passes. The inner end of the rib part I passes beyond its socket I sufficiently far to hinge the stretcher thereto. Placing the pivotal points-B of the rib parts H and I un,

er the rib enables me to present a smooth comparatively unbroken upper surface for the cover. I The umbrella being folded as represented in Fig. 2, it will be seen that the joints B of the cover-supporting ribs and between the ribs and stretchers are at the lower or handle end of the stick and held closelyithereto by a depression 6 in the under side of the handle. To open the umbrella, it is held in one hand, the other hand drawing out the handle E for a short distance to release the ribs and stretchers, which spread out, asindicated in dotted lines in Fig. 2, they having been drawn inward for engagement with the handle and held by the handle under spring tension by reason of the stretchers 0 bearing against and being intermediately held out from the stick by the enlarged portion D of the runner D.

The hand which heretofore held the umbrella The catches a a then spring into place and length. 7

lock the stick. The runner is then drawn doWn until it is can ht by the snap L. The ribs Will then be fulIy spread.

The cover is fastened at the ends of the ribs and at other suitable points thereon. I also propose to carry the ribs in pockets formed bythe cover-seams.

Having thus described the invention, what is claimed is 1. In an umbrella, the combination of a stick comprising three telescopic sections, means for holding said sections extended, a runner slidable'on the upper stick-section and having an enlarged portion to receive the intermediate stick-section when the stick is telescoped, folding supporting-ribs pivoted,

to the upper stick-section, each rib comprising two parts having'sockets at their meeting ends pivotally connected with each other, the socket on one part havin a hook to engage the other part and the latter having a pivot-lug, stretchers pivoted to the runner and to the pivot-lugs of the ribs and adapted to engage intermediately of their ends the enlarged portion of the runner and to be held away from the stick thereby when said stretchers and ribs are closed,- and a handle on the lower stick-section provided with a depression to receive the hinged ends of the folded ribs and stretchers when the latter are drawn toward the stick, whereby the joined ends of the ribs and stretchers will be held under spring tension, substantially as described.

2. In a folding umbrella, the combination of ribs, each formed in two parts, a socket on each part having a lug for a hinge-pin, and a finger or hook projecting from the socket on one part adapted to support the second part when extended.

8. In a folding umbrella, the combination of ribs each formed in two parts, a socket on each part having a lug for a hinge-pin, a finger or hook projecting from the socket, on one part adaptedto support the second part when extended, and a stretcher pivoted to the end of said second part.

In testimony whereof I aflix my signature in presence of witnesses.
